The illness benefit finding can have an impact on the physical and mental health of caregivers and the care outcomes of patients. Studies have shown that interventions can improve caregivers' illness benefit finding. Through literature review, this paper systematically summarizes the current domestic and foreign intervention strategies for illness benefit finding in caregivers of cancer patients, including cognitive behavioral therapy, yoga therapy, internet-based interventions, writing interventions, and coping skills training, continuing nursing, and other intervention strategies. This article aims at providing a reference for the caregivers of cancer patients to formulate targeted interventions and improve their illness benefit finding.
